Understanding the role of a nanotube host in stabilizing carbyne


Carbyne is a very reactive carbon allotrope that can be stabilized as ultra-long chains inside nanotubes. Two recent highlights of T. Pichler's group show how nanotube chirality determines the properties of encapsulated carbon chains and how their extraction via density gradient ultracentrifugation unravels the role of the carbon nanotube host. These results pave the way for the future application of these materials in sensing and optoelectronics.

These publications in ACS Nano and Nano Letters are resulting from a close cooperation between T. Pichler's group and L. Novotny's group at ETH Zürich, K. Yanagi's group at Tokyo Metropolitan University, and U. Kaiser's group at the University of Ulm.
